What is best in life? To crush your colleagues, to see them driven before you as you chase them around the office with perhaps the most powerful Nerf gun yet.

PopMech just got a sneak peek of the Nerf N-Strike Elite Demolisher 2-in-1 Blaster prototype. Nerf is still working out the final version to be released this fall, but you can expect to see the gun at toy fairs beginning with the U.K. Toy Fair starting tomorrow.

The 2-in-1 gets its name from its ability to bombard with two kinds of foamy munitions. This Nerf rifle will rapid-fire small darts, the company's Elite ammunition, from a magazine that contains up to 10 at once. Four AA batteries power this semi-automatic firing setup. Beneath the muzzle, there's a second barrel that will launch a fat Mega dart via pump action, and a location in the butt end of the rifle to store a second shot.

Nerf fanatics who love customization shall not be disappointed. The butt can be swapped out for other accessories. Nerf will sell laser sights for the foam sniper in you. Need to fire more than 10 darts at a time? Swap out the magazine for drum that can hold enough Elite ammunition to peg everyone you know.
